To all whom it may concern:

Be it known that 1, JOHN E. CRANNY, a citizen of the United States,residing at Omaha, in the county of Douglas and State of Nebraska, haveinvented certain new and useful Improvements in Attachments forLine-CastingMachines, of which the followinois a specification.

lhi's invention has for its object to provide a device which maybeapplied to line casting machines to prevent injury to the liners. Thedevice may be used in connection with any line casting machine lIlWhlChprinting-slugs or bars are cast in a slotted mold and deliveredtherefrom by an ejectorblade moving from the rear against the edge ofthe slug, the liners being removably placed in and occupying a part ofthe molds, said liners being variable in length to pro duce slugs foruse in printing columns or pages of different widths. While thelnvention may be used to advantage in connection'with the commercialMergenthaler linotype machine, it may be applied to any analogousmachine.

The invention consists of the novel construction, combination andarrangement of parts as described herein and claimed, and as illustratedin the accompanying drawings, it being understood that changes in size,form, proportions and minor details, may be made if desired, saidchanges to be within the scope of the invention as claimed.

In instances where frequent changes are required to form slugs whichvary in length the liners must be manually changed by an operator, andwhile said liners are suitably numbered to visibly indicate theirlength, mistakes occasionally occur in their selection, the result beingthat the liners become injured or broken since the length of a selectedliner may not correspond with the length of movement of the sliding-bar,the distance to which the latter moves operating to control the numberofejector-blades or ejector sections which move into engagement with theslug.

By use of theherein described device injury of a liner will not occur,since the sliding-bar will have a movement corresponding to the lengthof the slug to be ejected, and the ejector-sections will not engage theliner. 7

In the drawings, which illustrate one embodiment of the invention,;Fig.1 is a broken away view showing the front side of a molding-disc andcertain mechanism mounted upon the frame of a line casting machine. F1g. 2 is a plan view of a rock-lever. Fig. 3 is an enlarged detail,partly broken and'in section, showing a plunger-bar and parts connectedtherewith. Fig. 4 is a plan view, partly broken awayand in section,showing parts of a line casting machine with the device mounted thereon.Fig. 5 is a detail relating to Figs. 1 and 4, being a view in sideelevation of the ejector case and parts connected therewith. Fig. 6 is aview in front elevation showing a part of the machine frame and parts ofthe device mounted thereon, Fig. 7 is a plan View of the parts shown 1nFig. 6, apart of a molding disc being added. Figs. 8 to 13 inclusive areside views of liners. Fig. 14 is a sectional view on line I l-14 of Fig.13.

Referring now to the drawing for a more particular description, theattachment is shown and described in connection with the molding-disc l,the rock-shaft 2 known as the distributor mechanism space-band armshaft,the machine frame 3, the ejector-blade control rod 4: and thesliding-bar 5 which moves the ejecting-blades 6 forwardly in the casing7 of a line-casting machine.

Numerals 8 (Figs. 8 to 13) indicate liners of various lengths, and itwill be understood that, in instances where comparatively a narrowcolumn and short slug is required, a liner 8 is selected by an operatorand is placed inthe mold 9, the liner thus selected being of greaterlength than would be used in forming slugs for a wide column. Ittherefore follows, that the length of a slug a depends upon the lengthof the linerselected, since the part unoccupied in the mold 9, by theliner, is the part in which theslug is formed or molded, and it alsofollows that if a lineighaving too great a length is placed in the mold,the forwardly movable ejectorblades 6 which operate to move the slugfrom the mold, will engage and will injure the liner.

In order that injury to the liners may be avoided certain features ofconstruction are provided which are of a simple nature and will bepractical and operative in use, and now to be described.

The liners are provided with apertures b, the diameter of the apertureof each liner being specific and differing from that of the otherliners. Numeral 10 indicates a plunger-bar provided at one of its endswith a tapered pin 1, said pin preferably being removably mounted uponsaid bar by a keeper 12'. The plunger-bar is slidingly mounted inbrackets 13 which are secured to the frame, and is so disposed that whenthe molding-disc moves and disposes the mold 9 at ejecting position(Figs. 1, 4;), said bar will be disposed adjacent and at right-angles tothe liner.

Numeral 1% indicates a spring operative for moving the plunger 10 in adirection of the liner 8 to cause the pin 11 to enter the aperture Z) ofthe liner, subject to a control of certain devices.

I provide an arm 15 which is mounted upon therock-shaft 2 of themachine, said arm, during one of the movements of said shaft engaging aprojection 16 of the plunger-bar and moving said plunger outwardlyagainst the force of the spring 1%, the movement of the rock-shaft 2 inthe opposite direction operating to release the plunger-bar and topermit it to slide toward the molding disc, said sliding movement,however, being subject to the control oi a bellcranlr 17 having an arm 0adapted to engage in a recess (4' of the control-rod 4.

A rock-lever 18, pivotally mounted at 1' upon the machine frame has anarm f engaging in a slot g of the plunger-bar, its opposite arm beingpivotally connected with a link it having a pivotal connection with thecontrol-rod l, and it will be understood that if the bell-crank is movedagainst the force of its spring on (Fig. 7.) so that its arm 0 will bereleased from the recess d the plunger-bar will have a forward movementto permit the tapered pin 11 to enter the aperture b of the liner.

Numeral 19 indicates a spring connected with the machine frame and withthe reels lever 18, said spring having lesser degree of resiliency thenthe spring 14-, but operative, when the spring 1 1 is extended, to movethe control-rod 4i upwardly to permit engagement of the arm 0 of thebell-crank in the recess 0? of the control rod l. 2() is indicated arock-shaft having one arm n pivotally connected with the control-rod aand having an arm 29 which carries a. rod 21 (Fig. 5.) which carries thesliding-bar 5.

As thus described the bell-crank o tierates as a stop for preventing anylongitudinal movement of the control rod 4. In operation, the movementof the molding disc longitudinally of its axis is depended upon forreleasing the arm 0 of the bell-crank from the recess 01, themolding-discs of line casting machines having such forward movement ofapproximately one-half of an inch after they move to ejecting position;and in operation, the disc, when moving forwardly, will engage one armof the bell-crank and will cause a swinging movement thereof against theforce of its spring m, with the result will cause an outward movement ofthe plunger-bar 10 and the pin 11 against the force of the spring 14,the control rod 1 moving upwardly by operation of the spring 19, untilthe recess 03 receives the arm 0 of the bellcrank 17. The arm 15 thenhas a swinging movement toward the molding disc, but the plunger-barwill not be moved by action of the spring 14E since the arm 7' of therock-lever 18 engages an adjustingplate 5' of the plunger-bar, thebell-crank operating to prevent any downward movement of the control-rod1, and the plungerbar will remain stationary until the molding-disc,while in ejecting position, moves forwardly in line with its axis, andcauses the release mentioned of the arm 0 from the recess {2 of said rod4; and as soon as this release occurs the plunger-bar, by action of thespring 14, will move forwardly, its tapered pin 11 entering the aperture6 of the liner.

By referring to Fig. 14 it will be seen that the walls of the aperturesb are formed inclinedly, this feature being of advantage to preventundue wearing away of the walls which might be occasioned by engagementsif the tapered pin therewith. However, the parts are so proportionedthat while the pin enters apertures b with a certain force, said forceis sufficient only to insure suitable engagement.

It is obvious that the distance to which the plunger-bar and pin will.move forwardly will depend upon the diameter of the apertures b of theliners, and it is apparent that the distance to which the rod 4: will bemoved downwardly will depend upon the extent of the forward movement ofthe plunger, and these are desirable features since the upward movementof the sliding-bar 5 will correspond, as to distance, with the downwardmovement of the rod It follows, therefore, that the number ofejector-blades 6 to be moved forwardly in the casing 7 will depend uponthe size of the apertures Z) provided for the liners 8, the movements ofthe rod 4 and bar 5 being greater if the size of the aperture in a lineris greater, and their movements being lesser if the liner is providedwith an aperture of lesser size; for instance, if a liner has a lengthadapted for use in forming a column requiring 10 crime, said liner willhave an aperture 6 so proportioned that the tapered pin may enter such adistance that the bar 5 will move upwardly far enough for moving therequisite number of ejector blades forwardly for engaging a slugrepresenting 10 ems in length, the remaining ejector blades not beingdisturbed;

and if a liner used has a comparatively large aperture adapted for usewherea column of 20 ems is required, it is obvious that the bar 5 willbe moved upwardly a greater distance than in the first instancementioned.

The use of the device will be appreciated by operators of linotypemachines since there will be no uncertainty in operation or risk ofbreakage or injury of the comparatively expensive liners; also noattention of an operator will be required for adjusting the ejectorcontrol-rod 4.

While in the drawing I have not shown the mold 9 to be provided with anyaperture for receiving the tapered pin, to permit the liner and itsapertured terminal, during operation, to be disposed within the mold,and while in Fig. 1, I have shown a liner having a terminal partextending somewhat above the mold 9, this feature is not material, and Imay provide apertures b in any desired part of the liners.
